UNITED STATES SAMUEL L. ALLEN, OF MOORESTOWN, NEW JERSEY.

CULTIVATOR.

Specification of Letters Patent.

Patented Aug. 7, 1906.

Application filed March 29, 1905. Serial No. 252,659.

To all whom it may concern:

Be it known that I, SAMUEL L. ALLEN, a citizen of the United States, and a resident of Moorestown, county of Burlington, State of New Jersey, have invented certain new and useful Improvements in Cultivators, of which the following is a full, clear, and complete disclosure.

The object of my invention is to produce such a construction in cultivators that the same maybe adapted to a great variety of uses, and also that the same may be more easily adjustable and the parts more firmly helld in position than heretofore has been possib e.

Briefly, my invention comprises a gangframe having a rear tool-carrying bar to outward to provide 1 a part thereof, in which which the tools are adjustably clamped, said tool carrying bar having adjustable end portions which may be moved inward and the whole machine-frame, While at the same time I would provide means for holding said adjustable parts firmly and rigidly in position, but allowing the same to be quickly and easily adjusted.

My invention also comprises means for lowering and raising and fixing the height or position of the machine-frame in relation to the running-gear and the surface of the ground.

For a full, clear, and exact description of this embodiment of my invention reference may be had to the following specification and to the accompanying drawings, forming Figure 1 is'a side elevation of my improved cultivator. Fig. 2 is a plan-view thereof, the

seat being shown in dotted lines. Fig. 3 is a longitudinal sectional view taken substantially upon the line 3 3, Fig. 2. Fig. 4 is aperspective view of the details of the mechanism for adjusting the height of the machineframe and tools carried thereby in relation to the surface of the ground. Fig. 5 is a perspective view of the details of the extension to the tool-carrying bar, and Fig. 6 is a plan view of a modified form of construction for giving a greater effective width to the cultivatorframe without the use of extensions on the tool-carrying-b ar.

Referring to the drawings, the numeral 1 indicates the main axle upon which the supporting-wheels 2 2 are adapted to rotate. The wheels 2 2 may be held in position upon theaxle and in a suitable manner, but I have a greater or less width to construction, as shown, the collars being made adjustable upon the axle by means of a series of holes 1 through which the split pin may pass. Rigidly attached to the end of each axle.v or formed integrally therewith and extending at substantially right angles thereto are connecting bars or links 3, which are adapted to assume any an le in relation to To the en s of the links 3' the horizontal. are pivoted the two parallel ends of a substantially rectangular frame 4 by means of bolts 5. The forward bar of the frame 4 is preferably slightly offset forwardly at its central portion, as indicated at 6, so as to engage the tongue at a point somewhat in advance of the other portions of the frame. The rear side of this frame 4 is preferably formed by a single bar 7, which is attached to the end bars of the frame 4 by means of bolts 8, which have their heads countersunk in the bar 7, so as to not obstruct or interfere with the other parts of the frame, hereinafter to be mentioned. Said bar 7 is provided at its ends with laterally-extending lips or flanges 7. The end bars of downwardly and then upwardly, so as to engage the rear side'of the bar 7, as indicated in dotted lines in Fig. 5, thus forming a head adapted to be held in position by means of the bolt 8. Suitable brace-rods 9 of a shape similar to the end bars of the frame 4 are placed at points intermediate the ends of said frame to stiffen the frame transversely and to more evenly distribute the pull of the draft mechanism upon the entire tool-bar.

To the tool-b ar 7 is attached a pair of angle irons 10, the inwardly-extending portions of which are enlarged and extend parallel and vertically at a sufiicient distance apart to provide space for the reception of the end of the tongue 1 1, said angle-irons being provided with a series of holes 12 to allow of adjust ment of the angle of the tongue 11 in relation to the frame of the machine, the tongue 1 1 being provided with a hole through which is adapted to pass a bolt 13 to connect the tongue with the angle-plates 10. The tongue 11 is held in position above the forward bar of the frame 4 and above its central portion 6 by means of a U-shaped metallic strap 14, which is bolted to the front bar 6 and is connected with the tongue 11 by means of a bolt 15. This construction practically makes the tongue a part of the frame, particularly in relation tothe lifting mechanism hereinafter the frame 4 are-preferably curved preferably employed the split-pin and collar to be referred to. As means for attaching the draft mechanism to the frame of the machine I provide a doWnwardly-proj ecting part 16, consisting of two parallel bars connected 5 at their lower ends and which are bolted at their upper ends to the tongue 11 by means of a bolt 17. Abrace 18 connects the lower end of the part 16 with the rear portion of the tongue 11. The parallel bars constituting the part 16 are provided with a series of holes 19, by means of which the height of the point of pull of the draft mechanism may be varied. The draft mechanism may consist of the usual whiffletree 20 and the doubletree 21.

i The ends of the rear tool-bar 7 are provided with a pair of adjustable extensions 22, which are curved transversely at their outer ends to form arcs, as indicated at 23, and provided with a pair of lips or flanges 24, between which pass the forward brace-bars 25, said brace-bars being provided with longitudinal slots 26, adapted to engage bolts 27, carried by the extension-bars 22. The forward end of each brace-bar 25 is pivoted in relation to the frame 4 by meansof a U-shaped block 28, which is bolted to the end of the frame 4 and which is provided in its lower end with a slot into which passes the end of said brace-bar 25, said bar being retained therein by a pin or bolt 29. The inner end of the extension-bar 22 is clamped to the end of the tool-bar 7 by means of a U-shaped clamp 30, which also holds the tool-standard 31 rigidly in position. The lips 7 prevent any upward movement of the extensions 22 due to forcing the blades into the ground. The U-shaped clamps 30 consist of U-shaped metallic straps having slots in their outer ends and provided with a screw or bolt 32 for drawing the tool-standard 31 firmly against the tool-bars. The clamps which secure the other tool-standard to the tool-bar are substantially the same as that i just described, with the exception that the arms of the U-shaped strap are somewhat shorter, as they do not have to embrace the extension-bars 22.

It will now be evident that in the adjustment of the extension-bars 22 the curved portion of the brace 25 may slide upon the curved ends of the bars 22, and the variation in the length of the hypotenuse of the triangle formed by the frame 4, extension 22, and brace 25 is provided for, while at the same time the parts may be clamped rigidly and accurately in position.

The means for raising and lowering the tool-frame consist of the following parts: To 'the axle 1 is attached a U-shaped bar 33, which terminates in transversely-extending foot-pieces34. Upon each of the sides of said U-shaped bar is riveted a plate 35,which extends substantially at right angles to said sides and constituting therewith a bell-crank lever. At the upper ends of these plates 35 are pivoted two bars 36, which unite midway midway between the points where they are attached to the plates 35 and the point of convergence or unionare bolted or riveted angleplates 39, which carry at their lower ends a roller 40, which is adapted to bear underneath the tongue 11 and have a longitudinal movement thereon.

For the purpose of holding the lever 36 in its correct relation to the tongue .1 1 and to determine the depth of the cut when the blades are in their operative position in the ground I provide a screw-threaded rod 41, which is j ournaled in a block 42, secured between the diverging portions of the bars 36 by the bolt 37, the said block 42 having a screw-threaded hole therein and said rod 41 terminating in a crank-handle 43. The lower end of the screw-threaded rod 41 rests upon a rooved hock 44, carried by the tongue 1 1 and preferably located between the upper ends of the depending bars 16.

It will now be seen that the whole frame 4 will be supported upon the axle 1 through the plates 35 and the bars 36 and lever 36 since the tongue 11 is supported upon the roller 40 and held in its requisite position in relation thereto by means of the hand-screw 41. However, the weights supported by these parts are not affected by the draft u on the machine, as such draft is substantia ly in a straight line with the tool-standard 31 and the blades 45, carried thereby, and although the main frame is fixed in position by comparatively light parts and by the lever 36, yet there is no great strain upon them and the only actual weight that they have to support is that of the operator and the weight of the gang-frame and connecting parts.

When it is desired to raise the blades from the ground by elevating the gang-frame, the feet of the driver or operator are placed upon the foot-levers 34 and the lever 36 is grasped by his hand. Then in pushing downwardly with the feet and pulling upwardly with the hand the roller 40 is raised and travels on the under side of the tongue 11 as the blades at 35 are rotated with the axle 1. The roller 40 on being raised carries with it the tongue 11, and as the latter is fixed in relation to the main frame said main frame must also be raised, carrying with it the tool-standard and tools or blades.

When the gang-frame is once raised, it is only necessary to hold the lever 36 in its new position in order to keep the blades of the cultivator free from the ground. This is done by the following means: To the seat- ICC support 46, which is preferably attached to the tongue 11, is bolted two angle-irons 47, to which is pivoted a bar or tie-rod 48, having in its under side an inclined slot or notch 49. This slot 49 is adapted to engage the bolt 38 or other suitable projection when the lever 36 is in its highest or raised position.

In Fig. 6 I have shown a modified form of means for securing the outer tool-standard beyond the extreme limit of the main frame. In this modification the extension-bars 22 are omitted and the outer tool-standard is secured directly to the end of the side framebar of the frame 4, suitable Washers or separators, having inclined ends 50, beinginterposed between the side of the frame and the tool-standard. By rotating the Washers or separators the amount the outer blades project beyond the frame may be varied.

Having thus described my invention, I do' not wish to be understood as being limited to the exact details of form and arrangement of parts of the device herein set forth, for changes may be made in the form, arrangement, and proportion. of parts without departing from the spirit and scope of my invention; but
